Physics; Color science

A perceptual phenomenon in which the color of an area is perceived as closer to the color of the surround than it would if viewed in isolation. Assimilation occurs with stimuli with fine spatial ...

purity

Physics; Color science

The ratio of two lengths on a chromaticity diagram, the first length being the distance between the point representing the specified achromatic stimulus and that representing the color stimulus being ...

Bezold-Brücke hue shift

Physics; Color science

A shift in apparent color of a stimulus towards yellow or blue with increasing intensity. If a pair of long wavelength lights differing only in intensity are compared, the higher intensity stimulus ...

spatial contrast

Physics; Color science

A difference in some visible property between one area of a scene and adjacent areas. Black letters on a white background display high spatial contrast.

confusion line

Physics; Color science

A line on a chromaticity diagram representing colors that are not discriminable by a subject with a particular defect of color vision. The protan confusion line represents colors that are ...
